The presentinvention relates toioar lock construction, -andfmore particularly"to oar Theprimary object 'of ythe* invention yis to provide an oar lockwhich'will movevv laterallyof thek shell while lthe same'is inV use,

thereby permitting the handle 'portion of' the oar to movelongitudina'lly of the keel ofV the shell through thefentire stroke and; re-k covery, instead ofinthe arc off a. circle as lock. Y'

Another important object Vof theinvention is ithe universal practice with the fixed oar is torprovide means for supporting' an oarinl such a way that the oarsma'n may swing his body in a straight'line, eliminating body twisting and y swinging across the vshell on 'each stroke and recoveryfto throw the boat off ofitsv balance. .f i p' ,f

A stillv further object ofthe Yinvention is Vto provide means whereby the length of the view which will appear as the'description; proceeds, the invention resides inthe com-K usual oars may be ncrea'sed,--fthereby ina. creasing the leverage creating a greater re? action. against the oar lock, which; reaction inv turn tends to drive the shell.

` lVith the foregoing and other objects* in bination vand arrangement of parts'an'd :in

, thefdetails. of construction hereinafter described and claimed, it being understood that changes in the yprecise embodiment of the Ainvention herein disclosed, may be made within the scopel of what isr claimed, Withoutv departing from the spiritv'of theinvention.
